The nurse is caring for a patient with syndrome of inappropriate antidiuretic hormone secretion (SIADH) who has a serum sodium level of 118 mEq/dL and symptoms of fluid overload
Which IV fluid will the nurse expect to administer to this patient in order to correct the patient's fluid imbalance?
a.
0.33% normal saline
b.
0.45% normal saline
c.
0.9% normal saline
d.
3% normal saline
ANS: D
A hypertonic 3% saline solution will be used to correct the patient's hyponatremia and fluid overload that have developed as a result of SIADH. A 0.9% normal saline solution can be used once the serum sodium level has been raised nearer to normal range. A 0.45% or 0.33% normal saline solution is hypotonic and will only worsen the patient's fluid overload and hyponatremia.
